Mission summary

Kirk, Spock, and McCoy beam down to planet Holberg 917G in search of pure ryetalyn, the only known cure for a deadly outbreak of Rigelian fever on Enterprise. If they can’t secure this maguffin and process it in four hours, McCoy says “the epidemic will be irreversible.” They certainly don’t have time to investigate the life form that Spock’s tricorder registers on the supposedly uninhabited planet, nor is it a convenient moment for a floating robot to wobble over and fire a blue laser beam in their general vicinity. But these things happen, so what are you going to do?

Mission summary

Enterprise is on an important humanitarian mission to decontaminate Ariannus, which has succumbed to bacterial invasion that will kill billions of people without their timely intervention. But a funny thing happens on the way to the planet: they encounter a damaged Starfleet shuttlecraft which was jacked from Starbase 4. The lone pilot is injured and unable to respond to their hails, so they bring the shuttle onboard. Captain Kirk and Mr. Spock meet it at the hangar deck with a security team and a man in blackface stumbles into the corridor. But wait! He collapses and rolls over to dramatically reveal that the left side of his face is white!

Mission summary

Kirk, Spock, and McCoy are escorting Assistant Federation Commissioner Nancy Hedford in the shuttlecraft Galileo to the Enterprise for emergency medical care. In the middle of delicate negotiations on Epsilon Canaris III, she contracted Sakuro’s disease, a rare illness that is fatal if left untreated. She’s anxious to get back to prevent a war, but when they’re only four hours away from rendezvous with the ship, scanners pick up a weird cloud in space blocking their way. Hedford whines about the situation, but that has no effect. The cloud sucks the shuttle in and whisks them off course.

Mission summary

The Enterprise is enroute to the New Paris colony on Makus III to deliver medical supplies to victims of an ongoing plague, when Captain Kirk gets distracted by a shiny quasar, Murasaki 321. Galactic High Commissioner Ferris, a grumpy officer in fancy duds, objects to stopping to investigate, but Kirk insists his mission includes scientific study of cosmic phenomenon. They dispatch shuttlecraft 7, the Galileo, to take a closer look with seven crew members on board: Mr. Spock, Dr. McCoy, Mr. Scott, Lieutenant Boma, Mr. Gaetano, Mr. Latimer, and Yeoman Mears. It shouldn’t take long to get some readings and return to the ship and resume their journey to Makus III.
